We may get some benefit form considering other standardisation activity in this domain?
RFC3986 defines the generic syntax for the Universal Resource Identifier (URI) https://tools.ietf.org/html/rfc3986 As netCDF variables are resources that are being identified within the domain of a netCDF file, could we benefit from just adopting RFC3986? This has a reserved character section: https://tools.ietf.org/html/rfc3986#section-2.2 Disclaimer: I have not cross referenced this in detail with the NUG to examine consistency or problem areas (potential for contribution if useful) First glance, these look pretty similar. If these are consistent, then adopting the NUG definition unchanged looks sensible to me. It already mandates against the use of a '/' character, which is the most problematic one for me, given groups and variable identity within groups. I'd like to see an explicit reference to the relevant NUG section in the text or linked, as I had to search a bit and I know what I'm looking for I think: https://www.unidata.ucar.edu/software/netcdf/docs/netcdf_data_set_components.html#Permitted is stable enough for a standards document (@ethanrd do you agree this is a stable URI for the resource please?) mark -- You are receiving this because you are subscribed to this thread.
